I use 4350 for my '06 sako, 4895 in my garand, winchester wst in my 45, for cast bullets in various rifles I use IMR4759, 38 special titegroup, M! carbine cannot remember. So basically I'm using powders that I have used since I started reloading, which is over 40 years ago. So you could say that I'm using the older powders for the bulk of my reloading.I shoot cast bullets out of my Finnish M27 moisin nagant and my 30-40 krag. And hopefully so will be doing that with either black powder or triail boss. Thats for my 140+ year old peabody 50 caliber single shot. Thanks, Frank
